[Bet2502]

Just had this diagnosed as a fault on my E60, i have the idrive message
Fauly airbag/seatbelt restraint systems .....
Its been dagnosed by a non bmw garage as a faulty intelligent battery sensor
Anyone know of the approx costs of one of these from a stealer and if they can be bought used or not?
Cheers

Sorry I don't know the answer to your question but I have been googling and found that on early E60's the IBS can suffer with moisture Ingres, so that may be worth checking. The only thing I did find was that they cost £120.00 in 08. Hopefully somebody in the know will be along soon.
